It is not known whether nasal occlusion produces obstructive sleep apnea (OSA) by decreasing upper airway muscle activation via nasal reflexes or by increasing upper airway resistance and hence lowering the pressure in the pharnyx. The purpose of this study was to determine the effect of nasal occlusion on upper airway muscle activation. We studied seven men and measured alae nasi (AN) and geni...

Background. The frontal recess area represents a challenge to ENT surgeons due to its narrow confines and variable anatomy. Several types of cells have been described in this area. The agger nasi cells are the most constant ones. The frontal cells, originally classified by Kuhn into 4 types, have been reported in the literature to exist in 20%-41% of frontal recesses. Aim of the Study. To ident...

Depressor features have been described for many varieties of Wu Chinese, from Shanghai south to the Ou varieties of Wenzhou.
